Here are some interesting facts about the original Halloween by John Carpenter.
1. Due to its shoestring budget, the prop department had to use the cheapest mask that they could find in the costume store: a Star Trek William Shatner mask. They later spray-painted the face white, teased out the hair, and reshaped the eye holes. Shatner admitted that for years he had no idea his likeness was used for this film. It was only during an interview that someone mentioned his mask was being used. He has since stated that he is honored by this gesture.
2. As the movie was actually shot in early spring in southern California (as opposed to Illinois in late October), the crew had to buy paper leaves from a decorator and paint them in the desired autumn colors, then scatter them in the filming locations. To save money, after a scene was filmed, the leaves were collected and reused. However, asJamie Lee Curtis and John Carpenter note on the DVD audio commentary, the trees are quite full and green and even some palm trees can be seen, despite that in Illinois in October, the leaves would probably be mostly gone and there would be no palm trees.
3. According to screenwriter/producer Debra Hill, the character of Laurie Strode was named after John Carpenter's first girlfriend.
4. All of the actors wore their own clothes, since there was no money for a costume department. Jamie Lee Curtis went to J.C. Penney for Laurie Strode's wardrobe. She spent less than a hundred dollars for the entire set. She shot the film while on hiatus from the sitcom Operation Petticoat: Operation Petticoat.
5. The character of Michael Myers was named after the European distributor of Carpenter's previous film, Assault on Precinct 13 as a kind of weird "thank you" for the film's overseas success.
6. Carpenter approached Peter Cushing and Christopher Lee to play the Sam Loomis role (that was eventually played by Donald Pleasence) but both turned him down. Lee later said it was the biggest mistake he had ever made in his career.
7. The original script, titled "The Babysitter Murders", had the events take place over the space of several days. It was a budgetary decision to change the script to have everything happen on the same day (doing this reduced the number of costume changes and locations required) and it was decided that Halloween, the scariest night of the year, was the perfect night for this to happen.
8. According to Don Post Jr., President of Don Post Studios, the famous California mask making company, the filmmakers originally approached his firm about custom making an original mask for use in the film. The filmmakers explained that they could not afford the numerous costs involved in creating a mask from scratch, but would offer Post points in the movie as payment for his services. Post declined their offer, as he received many such proposals from numerous unknown filmmakers all the time.
9. The "Myers" house was a locale found in South Pasadena that was largely the decrepit, abandoned place seen in the majority of the film. However, as the house had to look ordinary (and furnished) for the early scenes with the young Michael Myers, almost the whole cast and crew worked together to clean the place, move in furniture, put up wallpaper, and set up running water and electricity, and then take it all out when they were through.
10. The wealthy film producer Moustapha Akkad had admittedly little interest in this film and helped make it primarily due to the enthusiasm of John Carpenter and Irwin Yablans. However, when the film turned out to be a huge box-office smash, Akkad saw an opportunity and facilitated every 'Halloween' sequel. This does not include the two remakes, which were produced after his death in 2005.
11. In the documentary short, Halloween 2000: Unmasked, it was revealed that the crew had chosen two masks for Michael Myers to decide on. The first was a Don Post Emmett Kelly smiling clown mask that they put frizzy red hair on. This was an homage to how he killed his sister, Judith in a clown costume. They tested it out and it appeared very demented and creepy. The other mask was a 1975 Captain James T. Kirk mask that was purchased for around a dollar. It had the eyebrows and sideburns ripped off, the face was painted fish belly white, and the hair was spray painted brown, and the eyes were opened up more. They tested out the Kirk mask and the crew decided that it was much more creepy because it was emotionless. This became the Michael Myers mask.
12. Laurie remarks that she would rather go out with unseen character "Ben Tramer". The name came from Bennett Tramer, an old college friend of director John Carpenter.
13. Carpenter wrote the part of Lynda for P.J. Soles after seeing her performance in Brian De Palma's Carrie.
14. Carpenter considered the hiring of Jamie Lee Curtis as the ultimate tribute to Alfred Hitchcock who had given her mother, Janet Leigh, legendary status in Psycho.
15. John Carpenter's intent with the character of Michael Myers was that the audience should never be able to relate to him.
16. Carpenter and co-writer Debra Hill have stated many times over the years that they did not consciously set out to depict virginity as a way of defeating a rampaging killer. The reason why the horny teens all die is simply that they're so preoccupied with getting laid that they don't notice that there's a killer at large. Laurie Strode, on the other hand, spends a lot of time on her own and is therefore more alert.
17. Prior to the movie, a book was written by Curtis Richards, and reveals more of the story behind Michael's rage. However, the book is very rare.
18. P.J. Soles went to a screening of the movie after it was released, sitting in the 4th row of a regular audience. She was very amused, when during her nude scene and line of "see anything you like?" a male audience member in front yelled out "hell yes I do!" unaware she was right behind him.
19. Michael Myers' full name is never mentioned in the final film. In fact, the only time anybody refers to him by name is in the opening scene.
20. Dr. Sam Loomis is Michael Myers' psychiatrist. Sam Loomis is also the name of Janet Leigh's secret lover in Psycho.
